FIELD

The present disclosure relates to quick assembly furniture, and more particularly to shelving or storage units wherein the side panels are connected to the back panel by folding hinges that can be locked into open positions via flexible fasteners. This configuration eliminates the need for any tools or know-how for assembly, and greatly enhances the packing efficiency and ease of assembly and disassembly of the unit.

BACKGROUND

Quick assembly furniture has become quite popular. Manufacturers of such furniture are called upon to offer inexpensive and easy-to-assemble furniture to consumers. Some furniture demanded by consumers, such as shelving or storage units, can be quite bulky and require a large amount of space in order to be shipped pre-assembled. In an effort to provide cost savings to consumers, manufacturers of quick assembly furniture seek ways to ship the furniture as inexpensively as possible.

In order to keep shipping costs down, furniture is typically shipped in multiple components that must be assembled by the consumer upon arrival. A shipment of multiple components of furniture may create problems. At times, components may inadvertently be left out of the shipping box when it is shipped. The packaging of the furniture may be damaged during shipping, resulting in tears to the shipping box and the loss of smaller components or the directions. Because the consumer must attach the hardware to the furniture components, the consumer is generally required to use tools and must, at times, follow complicated assembly instructions. Assembly performed by the consumer may not be as stable as factory assembly, due to the superior capabilities of factory assembly tools relative to the capabilities of tools normally available to or used by consumers. Additionally, once the furniture is assembled, it may be impossible or exceptionally difficult to disassemble the furniture without damaging the components.

FIG. 1A illustrates a conventional kit for a unit of furniture having a back panel 101 and side panel 102 that are assembled by an L-shaped bracket 111, nut 112, and screw 113. FIG. 1B illustrates another configuration of a back panel 101 and side panel 102 that are assembled by an L-shaped bracket 111, and two screws 113. FIG. 1C illustrates a third teaching in which a back panel 101 and side panel 102 are assembled by a flat bracket 114 and two screws 113.

In all of the configurations of FIGS. 1A-C, the consumer must possess the necessary tools to attach the back panels 101 and side panels 102. The necessary tools may include a hammer, a drill, a screw driver (which may be one of any size of a phillips head, flat head, square head, star head (available from Textron Indus., Inc. under the Torx® name), or other shape, and a wrench (which may be one of any size of an open-end, box-end, combination, flare-nut, ratcheting box, socket, etc.). Further, a consumer may need a requisite amount of physical strength to drive the screws into some panels. Once the kit is assembled, the unit of furniture is in its permanent final configuration, and it is only with great difficulty and potential damage to the unit that the unit can be disassembled.

The consumer must also possess the necessary know-how to assemble the kit. This means being able to read and follow any instruction manual(s) sent with the kit. At times, the instruction manual(s) may be complicated and/or confusing. At times, the instruction manual(s) may not be included with the kit or may be lost during shipment. At times, the language(s) of the instruction manual(s) may not be the language of the consumer. These situations lead to the consumer adopting a trial-and-error method to determine the correct configuration of the components. The consumer may waste time and energy building the wrong configuration, or may end with a sub-optimal unit due to less-than-optimal placement of all the components.

Conventional approaches for a manufacturer that does not desire to have the consumer assemble the unit using his or her own tools and/or follow an instruction manual, is that the unit must be assembled by the manufacturer prior to shipment. This assembly results in increased space required for shipping, and therefore increases costs.

A further aspect of prior art approaches is that consumers may damage portions of the kit, either during assembly and disassembly, or simply during the everyday use of the article of furniture. Such articles are often fabricated using materials such as particle board or medium density fiberboard (MDF), for example. Conventionally, the fully assembled product is a rigid item of furniture, suited for its designed purpose. However, these materials of construction may be vulnerable to failure when stresses are applied to connection points or joints. A joint is the close securing or fastening together of two or more smooth, even surfaces—customarily rigid. In formal furniture sold in assembled form, joints are typically secured by dowels, dovetails, dados, glue blocks, rabbets, etc. In kit or knock-down furniture, joints are commonly made rigid by custom connecting fasteners, connector bolts, or through-bolts mating with fixed nuts. A disadvantage with this approach is that the improper positioning of fastening elements during assembly may result in weakened connection points or joints. In addition, rigid designs may result in the imposition of full stress of use on even properly positioned connection points or joints, possibly leading to failure of connections. Kit or knock-down furniture is likely to be relocated or disassembled for transport, and the joints are weak points. It would be desirable to provide a kit of furniture adapted to such stress, while still amenable to easy assembly and disassembly.

In all of the configurations of FIGS. 1A-C, the consumer must possess the necessary tools and know-how to attach the back panels and side panels. Improper positioning of fastening elements during assembly may result in weakened connection points or joints. In addition, rigid designs may result in the imposition of full stress of use on even properly positioned connection points or joints, possibly leading to failure of connections.

There remains a need to simplify the process of assembling furniture while retaining the ability to ship the furniture in as small a container as possible. There also remains a need to create furniture that can be easily disassembled for transport to other locations.

The following description includes various embodiments and method of carrying out exemplary embodiments of the present approach. The description is not to be taken in a limiting sense, and is made merely for the purpose of illustrating the general principles of the present approach.

The present invention overcomes the limitations of the conventional furniture kits that are illustrated in FIG. 1A-C. Some embodiments have a back panel 101, two side panels 102, a base panel 103, and a top panel 104 that, when assembled, form a unit of furniture 140. The unit of furniture 140 uses hinges, position members, and flexible fasteners 117 to secure the unit of furniture 140 in lieu of nails, brackets, nuts, screws, or other comparable types of fasteners. The unit of furniture 140 may not require the use of tools in order to assemble the unit of furniture 140.

FIG. 2 demonstrates certain advantages of the present approach. FIG. 2A illustrates an embodiment of an assembled kit 140 with the reference axes shown and labeled. FIG. 2B illustrates a cut away view of the kit 140 in an open configuration. In one embodiment, the back panel 101 and side panels 102 are joined by one or more folding hinges 115. In the open configuration of this embodiment, the side panels 102 are at right angles to the back panel 101 and are substantially parallel to each other. FIG. 2C illustrates a cut away view of the kit 140 in a closed configuration. In this embodiment, the side panels 102 are folded in and are substantially parallel to the back panel 101. FIG. 2C is typical of the embodiment that would be shipped to the consumer, and FIG. 2B is typical of the embodiment that the consumer would make by unfolding the side panels 102 away from the back panel 101. A consumer needs to merely swing open the side panels 102 such that they are at right angles to the back panel 101 and are substantially parallel to each other. No tools are needed, and little, if any, know-how is needed, as the side panels 102 can only swing in one direction, away from the back panel 101.

The panels may be manufactured from particle board, MDF, plywood, hardboard, wood, metal, plastic, or any other appropriate material now known or later discovered. Each panel may be constructed of a different material. In some embodiments, a surface of the panels is coated in melamine. In some embodiments, the back panel 101 may be constructed of a material different than that of the other panels. For some manufacturers, the panels used may be constructed from a material that is vulnerable to failure when stresses are applied to connection points or joints. The improper positioning of rigid joints may result in weakened connection points or joints when stress is applied.

Each of the panels has a width. Some of the panels may have uniform widths. In other embodiments, the back panel 101 may have a smaller width than a width of the side panels 102. Alternately, the back panel 101 may have a smaller width than a width of the other panels.

FIGS. 3A and 3B demonstrate the ease of the base panel 103 assembly. FIG. 3A illustrates an upwardly facing support face defined by at least one rigid support plate 116 affixed to a lower portion of the side panel 102 that supports a base panel 103 at the base of the two side panels 102. The base portions of the side panels 102 face the back panel 101 when in a closed position and the at least one rigid support plate 116 extends along an x-z plane when the side panels 102 are in the open position. The at least one rigid support plate 116 may be attached in any manner of ways known in the art. In one embodiment, the at least one rigid support plate 116 may be welded to the lower portion of the side panel 102 by the manufacturer. In one embodiment, the at least one rigid support plate 116 is removably affixed to the side panel 102. FIG. 3B illustrates the configuration of the unit upon placement of the base panel 103 onto the one or more rigid support plates 116. A consumer needs to merely place the base panel 103 onto the support plates 116 that are attached to the side panels 102. No tools and little, if any, know-how is needed.

FIG. 4 demonstrates an approach by which the unit of furniture is made stable and yet can be assembled and disassembled in a quick and easy manner. FIG. 4 shows a cut away view of an embodiment of the unit and illustrates a configuration positioning a plurality of pre-installed flexible fasteners 117 that join the side panels 102 with the base panel 103. The flexible fasteners 117 may be installed in any manner of ways known in the art. The fasteners 117 lock the side panels 102 with the base panel 103 at right angles.

A toggle portion 131 of each fastener 117 may be mounted to the base panel 103 and a hook or toggle receptacle portion 132 of each fastener is mounted to the side panel 102. The toggle portion 131 reversibly attaches to the toggle receptacle 132 to lock the side panels 102 to the base panel 103 and restrict the side panels 102 from z-axis rotation and restrict the base panel 103 from y-axis rotation.

Base panel 103 has an outer surface, an inner surface, and a length that extends across the x-axis and is defined by two substantially parallel side edges. In some embodiments, at least one flexible fastener 117 is coupled proximate each of the substantially parallel side edges. In some embodiments, the flexible fastener 117 is coupled to the outer surface of the base panel 103. The flexible fastener 117 may further be coupled at approximately a center point of the parallel side edges. In some embodiments, a single flexible fastener 117 is used to couple each side panel 102 to the base panel 103. In other embodiments, each side 102 panel may contain a plurality of fasteners 117 that are coupled to the base panel 103. In other embodiments, the base panel 103 is coupled to the back panel 101 using at least one flexible fastener 117.

In embodiments where a single fastener 117 is used to couple each side panel 102 to the base panel 103, the fastener 117 is strategically placed and sufficiently flexible so as to allow some flexibility without causing damage to the underlying base panel 103 or side panels 102.

Each side panel 102 has a top surface and a bottom surface that extend across the x-axis when assembled, as shown in FIG. 5. Each side panel 102 further has an outer surface and an interior surface that extend across the y-axis when assembled. The interior surfaces are configured to face the interior of a case when the unit of furniture 140 is assembled. In some embodiments, the side panels 102 also include legs. In some embodiments, the flexible fastener 117 may be coupled to the bottom surface of the side panels 102. In embodiments in which the side panels 102 do not include legs, the flexible fastener 117 may be coupled to the interior surface of the side panel 102 proximate the bottom surface. The fasteners 117 may be coupled at approximately a center point of the bottom surface of the side panels 102, as is shown in FIG. 4. The toggle portion 131 of the flexible fastener 117 may be positioned on the outer surface of the base panel 103 to line up and interact with the toggle receptacle 132 of the flexible fastener 117 on the bottom surface of the side panel 102. As can be seen in FIG. 4, in this embodiment, the toggle portion 131 and toggle receptacle 132 interact in an x plane. In other embodiments, the toggle receptacle 132 may be coupled at approximately to the interior surface of the side panel 102 proximate a center point of the bottom surface, and the toggle portion 131 of the flexible fastener 117 may be positioned proximate the center point of the side edge of the base panel 103. In this embodiment, the toggle portion 131 and toggle receptacle 132 interact in a y plane. The fastener 117 acts to restrain relative movement of the side panels 102 with respect to the bottom panel 101 around the z-axis. The fastener 117 also acts to restrain relative movement of the bottom panel 101 with respect to the side panels 102 around the x-axis and the y-axis. The fastener 117 allows the unit of furniture 140 to use a small number of restraints such that the result of the overall structure is rigid. This is in contrast to prior furniture assemblies where an excessive number of rigid fasteners were used. Not only does the reduced number of fasteners reduce costs and avoids over-engineering, it simplifies the assembly process for the consumer.

The toggle portion 131 and toggle receptacle 132 may be mounted to the side panels 102 and base panel 103 by the manufacturer. The consumer merely needs to lock the corresponding toggle portion 131 and toggle receptacle 132 of the fastener 117 together to create a resilient, stabilized unit. In some embodiments, the side panels 102 may be reinforced proximate the fastener 117. In other embodiments, the base panel 103 may be reinforced proximate the fastener 117. The side panels 102 and base panel 103 may be reinforced with sturdier materials, increased flexibility of the material, or any other method in the art used to increase flexibility now known or later discovered.

Because the unit of furniture may be constructed from materials that may be vulnerable to failure when stress is applied, fasteners 117 that are resilient at the connection points may mitigate the risk of failure when stress is applied.

FIG. 5 illustrates the position of the top panel 104 onto the top surface of the side panels 102 and back panel 101. The top panel 104 is shown connected to the side panels 102 and back panel 101 by a plurality of position members 118 mounted to a top surface of the side panels 102 and a bottom surface of the top panel 104, with the position members 118 oriented along the y-axis. The top surface of the side panels 102 may have a plurality of recesses that are configured to interact with the plurality of position members 118. A top surface of the back panel 101 may have a plurality of recesses that are configured to interact with the plurality of position members. The position members 118 are shown in the figures as pins, but other embodiments of position members, such as biscuits, dowels, and splines may be acceptable alternatives, depending on the application and type of furniture. In some embodiments, the position members 118 are only coupled to the top surface of the side panels 102 and the bottom surface of the top panel 104. In other embodiments, the position members 118 are only coupled to the top surface of the back panel 101 and the bottom surface of the top panel 104.

The position members 118 fit into corresponding position member receptacles 119 on the opposite surface. The position members 118 restrict the top panel 108 from x and z axis movement. For this embodiment, a consumer need merely place the top panel 104 onto the top surface of the side panels 102 and back panel 101, aligning the position members 118 with the position member receptacles 119, to assemble the top panel 104. In some embodiments, the position members 118 have a uniform width or diameter. In other embodiments, the position members 118 may increase in width as they extend upwardly, and the recesses in the bottom surface of the top panel 104 may be keyhole recesses.

FIG. 6 illustrates the fasteners 117 that may be used to join the side panels 102 to the top panel 104. Top panel 104 has an outer surface, an inner surface, and a length that extends across the x-axis and is defined by two substantially parallel side edges. In some embodiments, the side edges of the top panel 104 may extend beyond the outer surface of at least one of the side panels 102. In some embodiments, the side edges of the top panel 104 extend beyond the side panels 102.

In some embodiments, the top panel 104 has at least one support beam coupled to the inner surface. In other embodiments, the top panel 104 may have a reinforced edge proximate at least one outer edge of the top panel. The reinforced edge may have an increased width than a width of the top panel 104, and the reinforced edge may extend downward from an outer surface of the top panel 104 along the y-axis. In some embodiments, the reinforced edge may extend along the perimeter of the top panel 104. The support beams and reinforced edge may assist in mitigating failure when stresses are applied to the top panel 104.

At least one fastener 117 may be coupled to the inner surface of the top panel 104. In some embodiments, at least one flexible fastener 117 is coupled proximate each of the substantially parallel side edges of the top panel 104. In some embodiments, the flexible fastener 117 is coupled to the inner surface of the top panel 104. The flexible fastener 117 may further be coupled at approximately a center point of the parallel side edges. In some embodiments, the fastener 117 may be coupled to a support beam. The flexible fastener 117 may be coupled to the support beam proximate a center point of the side panel 102 when the unit of furniture 140 is assembled.

There may be a single flexible fastener 117 used to couple each side panel 102 to the top panel 104. In other embodiments, each side 102 panel may contain a plurality of fasteners that are coupled to the top panel 104. In other embodiments, the top panel 104 is coupled to the back panel 101 using at least one flexible fastener 117. In one embodiment, a toggle portion 131 of each fastener 117 may be mounted to the side panel 102 and a toggle receptacle or hook portion 132 of each fastener may be mounted to an inner surface of the top panel 104. In another embodiment, a toggle portion 131 of each fastener 117 may be mounted to an inner surface of the top panel 104 and a toggle receptacle or hook portion 132 may be mounted to the side panel 102. The toggle portion 131 reversibly attaches to the toggle receptacle or hook portion 132 to release-ably lock the side panels 102 to the top panel. Once fastened, the fasteners restrict the side panels 102 from z-axis rotation and restrict the top panel 104 from y-axis rotation. The consumer merely needs to latch the toggle portion 131 to the toggle receptacle portion 132 to complete this portion of the assembly and create a resilient, stabilized unit.

In embodiments where a single fastener 117 is used to couple each side panel 102 to the top panel 104, the fastener 117 is strategically placed and sufficiently flexible so as to allow some flexibility without causing damage to the underlying base panel 104 or side panels 102. Flexibility may be desired in the event of improper placement of the connection points.

In some embodiments, the flexible fastener 117 may be coupled to the interior surface of the side panels 102. The fasteners 117 may be coupled proximate a center point of the top surface of the side panels 102. The toggle receptacle 132 of the flexible fastener 117 may be positioned on the inner surface of the top panel 104 to line up and interact with the toggle portion 131 of the flexible fastener 117 on the bottom surface of the side panel 102. In this embodiment, the toggle portion 131 and toggle receptacle 132 interact in a y plane. The fastener 117 acts to restrain relative movement of the side panels 102 with respect to the top panel 104 around the z-axis. The fastener 117 also acts to restrain relative movement of the top panel 104 with respect to the side panels 102 around the x-axis and the y-axis. The fastener 117 allows the unit of furniture 140 to use a small number of restraints such that the result of the overall structure is rigid. This is in contrast to prior furniture assemblies where an excessive number of rigid fasteners were used. Not only does the reduced number of fasteners reduce costs and avoids over-engineering, it simplifies the assembly process for the consumer.

The toggle portion 131 and toggle receptacle 132 may be mounted to the side panels 102 and top panel 104 by the manufacturer. The consumer merely needs to lock the corresponding toggle portion 131 and toggle receptacle 132 of the fastener 117 together to create a resilient, stabilized unit. In some embodiments, the side panels 102 may be reinforced proximate the fastener 117. In other embodiments, the top panel 104 may be reinforced proximate the fastener 117. The side panels 102 and top panel 104 may be reinforced with sturdier materials, increased flexibility of the material, or any other method in the art used to increase flexibility now known or later discovered.

In some embodiments, the top surface of the side panel 102 is configured to fit between a support beam and a reinforced edge of the top panel 104. In addition to using the position members 118 and the fasteners 117 to attach the top panel 104 to the side panels 102 and back panel 101, the support beam and reinforced edge may act to stabilize the side panels 102 and restrict movement of the side panels 102 relative to the z-axis. In some embodiments, the side panel 102 is lodged between the reinforced edge and a support beam of the top panel 104.

FIGS. 7A and 7B illustrate various embodiments of the flexible hook and toggle fasteners 117. The fasteners 117 may include a toggle portion 131 that is spring loaded 133, which provides constant tension for secure latching. A spring loaded toggle latch 133 makes the unit resilient upon loading and unloading due to its flexibility in range of motion. “Resilient” may be defined as fastening that permits a minor deformation at the joint, with the ability to return to shape after loading, but not so rigid as to damage the surrounding furniture material to which the fastener is mounted, as might occur with a glued or otherwise rigid joint of MDF, for example. As mentioned above, resiliency is important if the unit of furniture is constructed from materials that may be vulnerable to failure when stress is applied. “Deformation” in this context involves both extension and compression along the axis of any spring within fastener 117, but also rotation of the latching ring 142 about its mount on toggle portion 131 or about its connection point on toggle receptacle portion 132. Thus, the degree of resilience desired is a function of the specifications of any springs, as well as the relation of latching ring 142 to its mount or connection point design.

In some embodiments, the fastener 117 may include a hasp. In other embodiments, the fastener 117 does not include a hasp. In embodiments where the fastener 117 does not include a hasp, the toggle portion 131 and the toggle receptacle 132 interact in a manner to sufficiently fasten the fastener 117 without the use of a hasp or additional fastening mechanism. The fastener 117 may further be sufficiently flexible so that, in the event of operator error in appropriately aligning the panels, the panels may not deform when the fastener 117 is employed.

Optionally, one or more shelves 105 may be included to divide the case storage volume formed by the top panel 104, base panel 103, and side panels 102, as is shown in FIG. 8. The one or more shelves 105 are generally attached to the inside portion of the side panels 102 such that the shelves 105 extend along an x-z plane and are positioned between the side panels 102. The one or more shelves 105 can be attached in any manner of ways known in the art. In some embodiments, the one or more shelves 105 are coupled to the unit of furniture using flexible fasteners 117. In some embodiments, the one or more shelves 105 are coupled to the toggle portion 131, and the rear panel 101 is coupled to the toggle receptacle 132.

Optionally, one or more door panels 106 may be included to seal off all or a portion of the case storage volume formed by the top panel 104, the base panel 103, and the side panels 102, as is shown in FIG. 9. The one or more door panels 106 can be attached in any manner of ways known in the art. In some embodiments, the one or more door panels 106 are coupled to the unit of furniture using flexible fasteners 117. FIG. 9 shows one embodiment in which one door panel 106 closes off the space of the enclosure.
